Paper Bubble Making Machines

Paper Bubble Sheet Making Machine

The SD-PB600 converts kraft paper reels into embossed paper bubble sheets in a single continuous process. It forms cushioning sheets with air-like protection using a patterned die, suitable for e-commerce packaging and industrial shipping. The machine runs at 300 pieces per minute when producing 200x200mm sheets, allowing a packaging producer to make its own paper bubble wrap instead of buying finished rolls.

  • Replaces plastic bubble wrap with a paper cushion that is recyclable and accepted by retailers restricting plastics
  • Single-pass process for unwinding, embossing, and rewinding reduces manual handling and operator count
  • Produces 300 sheets per minute at 200x200mm size, matching high-volume e-commerce packing demand
  • Conveyor system feeds sheets directly to downstream packaging lines or stacking stations
  • Slitting blades allow custom sheet sizing to match downstream bagging or wrapping equipment
Problems It Solves

Why Buyers Choose It

  • Plastic bubble wrap is being restricted or rejected by end customers in export markets
  • Buying finished paper bubble sheets adds a supplier margin and long replenishment lead times
  • Manual wrapping of fragile goods is slow and inconsistent between shifts
  • Inconsistent sheet size or thickness from third-party suppliers causes packing line jams
  • Lack of local paper cushioning production forces reliance on imported rolls
Who It Is For

Who Runs This Machine

  • Protective packaging producers switching from plastic to paper cushioning
  • E-commerce fulfilment centres running high-speed automated packing lines
  • Paper converters adding paper bubble sheet capacity to their existing kraft paper processing
  • Poly bag makers supplying pre-opened bags on a roll who need inline cushioning
Application

Where This Machine Is Used

Process

How The Machine Runs

Step 1Load a kraft paper reel up to 600 mm diameter onto the 3 inch inflatable air shaft
Step 2Guide the web through the embossing die to form the bubble pattern
Step 3Use the conveyor to move finished sheets to the output station
Step 4Adjust slitting blades to cut sheets to desired size during production
Step 5Rewind finished sheets or stack them directly for downstream use

Materials

  • Kraft paper reels from 80 to 180 gsm
  • Optional laminated backing layer for improved durability
  • Paper with embossing pattern for air-cell formation

Quality Control

  • Web tension control ensures consistent cell formation across the sheet width
  • Slitting blades are checked regularly to maintain clean, straight cuts
  • Machine is test run with customer-provided kraft paper before shipment
  • Speed and die alignment are verified during the test run to match sheet output

Customisation

  • Embossing die can be changed to form different cell patterns or sizes
  • Slitting blades can be adjusted or replaced for different sheet dimensions
  • Power supply can be built to match the voltage and frequency of the destination country
  • Conveyor height and output direction can be modified for integration with existing lines

Certifications

  • ISO9001:2000 certificate obtained in 2005
  • CE certificate obtained in 2006
Comparison

How It Compares

Buying finished paper bubble sheetsConverting in house removes the supplier margin but requires inventory of kraft paper and machine investment
Plastic bubble wrap machinesPaper bubble is recyclable and accepted where plastics are restricted, though it is heavier per square metre
Paper bubble sheet cutting machineThis machine forms the bubble pattern; a cutting machine only trims finished sheets
Use Guide

Running It On Your Floor

  1. Load a kraft reel up to 600 mm diameter onto the 3 inch inflatable air shaft
  2. Set the desired sheet size on the slitting blades before starting the run
  3. Start at low speed and increase gradually to avoid web misalignment
  4. Check the first few sheets for consistent cell formation and clean slitting
  5. Keep the embossing die and slitting blades clean to maintain product quality
